Made incompatible client disconnect messages more informative

This can be enabled or disabled using the "online-mode" directive in
server.properties.

NOTE: For safety reasons it is enabled by default, since many naive server owners currently believe that authentication is not needed because "the client is forced to sign-in".
Newsflash for readers: the forced authentication is easily bypassed using a LAN proxy.

Un-authenticated LAN connections will still work fine if the online mode is disabled.

Added the following API methods:
- Server->getOnlineMode() : bool
- Server->requiresAuthentication() : bool
- Player->isAuthenticated() : bool

JWT verification is rather expensive, so it is done in an AsyncTask. Make sure you don't hog your worker threads.

 # PocketMine-MP Contribution Guidelines
 
-You must follow these guidelines if you wish to contribute to the PocketMine-MP code base, or participate in issue tracking.
-
-## I have a question
-* For questions, please refer to the _#pocketmine_ or _#mcpedevs_ IRC channel on Freenode. There is a [WebIRC](http://webchat.freenode.net?channels=pocketmine,mcpedevs&uio=d4) if you want.
-* You can ask directly to _[@PocketMine](https://twitter.com/PocketMine)_ in Twitter, but don't expect an immediate reply.
-* You may use our [Forum](http://forums.pocketmine.net) to ask questions.
-* We do not accept questions or support requests in our issue tracker.
 
 ## Creating an Issue
- - First, use the [Issue Search](https://github.com/PocketMine/PocketMine-MP/search?ref=cmdform&type=Issues) to check if anyone has reported it.
- - If your issue is related to a plugin, you must contact their original author instead of reporting it here.
- - If your issue is related to a PocketMine official plugin, or our Android application, you must create an issue on that specific repository.
- - **Support requests are not bugs.** Issues such as "How do I do this" are not bugs and are closed as soon as a collaborator spots it. They are referred to our Forum to seek assistance.
- - **No generic titles** such as "Question", "Help", "Crash Report" etc. If an issue has a generic title they will either be closed on the spot, or a collaborator will edit it to describe the actual symptom.
- - Information must be provided in the issue body, not in the title. No tags are allowed in the title, and do not change the title if the issue has been solved.
- - Similarly, no generic issue reports. It is the issue submitter's responsibility to provide us an issue that is **trackable, debuggable, reproducible, reported professionally and is an actual bug**. If you do not provide us with a summary or instructions on how to reproduce the issue, it is a support request until the actual bug has been found and therefore the issue is closed.
- - To express appreciation, objection, confusion or other supported reactions on pull requests, issues or comments on them, use GitHub [reactions](https://github.com/blog/2119-add-reactions-to-pull-requests-issues-and-comments) rather than posting an individual comment with an emoji only. This helps keeping the issue/pull rqeuest conversation clean and readable.
+- If you are reporting a bug:
+ - **make sure that you are using the latest supported version** before opening an issue.
+ - **test it on a clean test server, WITHOUT PLUGINS**, to see if the issue still occurs. If not then it may be a plugin issue. Please also indicate the result of such tests.
+
+- [Search the issue tracker](https://github.com/pmmp/PocketMine-MP/issues?utf8=%E2%9C%93&q=is%3Aissue) to check if anyone has already reported it, to avoid needlessly creating duplicate issues. Make sure you also check closed issues, as an issue you think is valid may already have been resolved.
+
+- If your issue is related to a plugin, **do not report here, contact the plugin's original author** instead.
+
+- **Support requests are not bugs.** Issues such as "How do I do this" are not bugs and will be closed. If you need help, please see [here](README.md#discussion) and do not misuse our issue tracker.
+
+- **No generic titles** such as "Question", "Help", "Crash Report" etc. A good issue report provides a quick summary in the title. If you just got a crash report but you don't understand it, please look for a line starting with `Message`. It summarizes the bug.
+
+- Information must be provided in the issue body, not in the title. No tags like `[BUG]` are allowed in the title, including `[SOLVED]` for solved issues.
+
+- Similarly, no generic issue reports. For bugs, it is the issue author's responsibility to provide us an issue that is **trackable, debuggable, reproducible, reported professionally and is an actual bug**.
+<br><br>Valid issue reports must include instructions how to reproduce the issue or a crashdump/backtrace (unless the cause of the issue is obvious).
+<br><br>**If you do not provide us with a summary or instructions on how to reproduce the issue, it will be treated as spam and will therefore be closed.**
+<br><br>In simple words, if the issue cannot be properly confirmed to be valid or lacks required information, the issue will be closed until further information is provided.
+
+- To express appreciation, objection, confusion or other supported reactions on pull requests, issues or comments on them, use GitHub [reactions](https://github.com/blog/2119-add-reactions-to-pull-requests-issues-and-comments) rather than posting an individual comment with an emoji only. This helps keeping the issue/pull request conversation clean and readable.
+
+- If your issue is related to the PocketMine-MP website, forums, etc., please [talk to a human directly](README.md#discussion).
+
+
 
 ## Contributing Code
-* Use the [Pull Request](https://github.com/PocketMine/PocketMine-MP/pull/new) system, your request will be checked and discussed.
-* __Create a single branch for that pull request__
-* Code using the syntax as in PocketMine-MP. See below for an example.
-* The code must be clear and written in English, comments included.
-* Use descriptive commit titles
-* __No merge commits are allowed, or multiple features per pull request__
+- To contribute code to the repository, [fork it on GitHub](https://github.com/pmmp/PocketMine-MP/fork), create a branch on your fork, and make your changes on your fork. You can then make a [pull request](https://github.com/pmmp/PocketMine-MP/pull/new) to the project to compare your branch to ours and propose your changes to our repository. We use the Pull Request system to allow members of the team to review changes before they are merged.
+
+- By proposing a pull request to the project, you agree to your code being distributed within PocketMine-MP under the [LGPL license](LICENSE).
+
+- At PocketMine, **we enforce a very high standard for contributions**. This is because PocketMine-MP and its related projects are used very widely in production. While this might seem like we are being mean at times, **our priority is what is best for PocketMine-MP itself**. We try to ensure that our project's codebase is as clean as possible and ensure that only top-quality material makes it through to PocketMine-MP itself. **If a contribution does not live up to our standards, changes may be requested or the pull request may be closed.**
+
+- **Your pull request will be checked and discussed in due time.** Since the team is scattered all around the world, your PR may not receive any attention for some time.
+
+- **Avoid using GitHub Web Editor**. The web editor lacks most useful GIT features and **should only be used for very minor changes**. It is immediately clear if the web editor has been used, and if so the PR is more likely to be rejected. If you want to make serious contributions, **please learn how to use [GIT version control](https://git-scm.com/)**.
+
+- **Do not copy-paste code**. There are potential license issues implicit with copy-pasting, and copy-paste usually indicates a lack of understanding of the actual code. Copy-pasted code is obvious a mile off and **any PR like this is likely to be closed**. If you want to use somebody else's code from a Git repository, **use [GIT's cherry-pick feature](https://git-scm.com/docs/git-cherry-pick)** to cherry-pick the commit. **Cherry-picking is the politer way to copy somebody's changes** and retains all the original accreditation, so there is no need for copy-pasted commits with descriptions like `Some code, thanks @exampleperson`.
+
+- In addition to the above, **make sure you can explain your changes**. If you can't provide a good explanation of changes, your PR may be rejected.
+
+- **Create a new branch for each pull request.** Do not create a pull request with commits that exist in another pull request.
+
+- **Code should use the same style as in PocketMine-MP.** See [below](#code-syntax) for an example.
+
+- **The code must be clear** and written in English, comments included.
+
+- **Use descriptive commit titles.** You can see an example [here](http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html).
+
+- **Try to stick to one change per commit.** This ensures that if you create a PR with several changes, we can decide which ones we wish to include and which ones not to include.
+
+- **It is inadvisable to create pull requests with large commits** unless this has been discussed with the team beforehand. Large pull requests are difficult to review, and such pull requests may end up being closed. The only exception is when all features in the pull request are related to each other, and share the same core changes.
+
+- **You may be asked to rebase your pull request** if the branch becomes outdated and/or if possibly conflicting changes are made to the target branch. To see how to do this, read [this page](https://github.com/edx/edx-platform/wiki/How-to-Rebase-a-Pull-Request).
+
 
 **Thanks for contributing to PocketMine-MP!**

 ### Code Syntax
 
 It is mainly [PSR-2](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-1-basic-coding-standard.md) with a few exceptions.
-* Opening braces MUST go on the same line, and MUST NOT have spaces before.
-* `else if` MUST be written as `elseif`. _(It is in PSR-2, but using a SHOULD)_
-* Control structure keywords or opening braces MUST NOT have one space before or after them.
-* Code MUST use tabs for indenting.
-* Long arrays MAY be split across multiple lines, where each subsequent line is indented once. 
-* Files MUST use only the `<?php` tag.
-* Files MUST NOT have an ending `?>` tag.
-* Code MUST use namespaces.
-* Strings SHOULD use the double quote `"` except when the single quote is required.

-## Bug Tracking for Collaborators
-
-### Labels
-To provide a concise bug tracking environment, prevent the issue tracker from over flowing and to keep support requests out of the bug tracker, PocketMine-MP uses a label scheme a bit different from the default GitHub Issues labels.
-
-PocketMine-MP uses GitHub Issues Labels. There are a total of 12 labels.
-
-Note: For future reference, labels must not be longer than 15 letters.
-
-#### Categories
-Category labels are prefixed by `C:`. Multiple category labels may be applied to a single issue(but try to keep this to a minimum and do not overuse category labels).
- - C: Core - This label is applied when the bug results in a fatal crash, or is related to neither Gameplay nor Plugin API.
- - C: Gameplay - This label is applied when the bug effects the gameplay.
- - C: API - This label is applied when the bug effects the Plugin API.
-
-#### Pull Requests
-Pull Requests are prefixed by `PR:`. Only one label may be applied for a Pull Request.
- - PR: Bug Fix - This label is applied when the Pull Request fixes a bug. 
- - PR: Contribution - This label is applied when the Pull Request contributes code to PocketMine-MP such as a new feature or an improvement.
- - PR: RFC - Request for Comments
-
-#### Status
-Status labels show the status of the issue. Multiple status labels may be applied.
- - Reproduced - This label is applied when the bug has been reproduced, or multiple people are reporting the same issue and symptoms in which case it is automatically assumed that the bug has been reproduced in different environments.
- - Debugged - This label is applied when the cause of the bug has been found.
- - Priority - This label is applied when the bug is easy to fix, or if the scale of the bug is global.
- - Won't Fix - This label is applied if the bug has been decided not be fixed for some reason. e.g. when the bug benefits gameplay. *This label may only be applied to a closed issue.*
-
-#### Miscellaneous
-Miscellaneous labels are labels that show status not related to debugging that bug. The To-Do label and the Mojang label may not be applied to a single issue at the same time.
- - To-Do - This label is applied when the issue is not a bug, but a feature request or a list of features to be implemented that count towards a milestone.
- - Mojang - This label is applied when the issue is suspected of being caused by the Minecraft: Pocket Edition client, but has not been confirmed.
- - Invalid - This label is applied when the issue is reporting a false bug that works as intended, a support request, etc. *This label may only be applied to a closed issue.*
-
-### Closing Issues
-To keep the bug tracker clear of non-related issues and to prevent it from overflowing, **issues must be closed as soon as possible** (This may sound unethical, but it is MUCH better than having the BUG TRACKER filled with SUPPORT REQUESTS and "I NEED HELP").
-
-If an issue does not conform to the "Creating an Issue" guidelines above, the issue should be closed.
-
-### Milestones
-PocketMine-MP uses GitHub Milestones to set a goal for a new release. A milestone is set on the following occasions.
-
- - A new Beta release
- - A new Stable release
-
-A milestone must use the following format:
-```
-Alpha_<version_number> [release_title][release_version]
-```
-For example:
-```
-Alpha_1.4 beta2
-```
